Up or down, sleek or tousled, there's a runway-inspired hairstyle that will work for you. Here's how to replicate the prettiest ones—straight from the pros working backstage at the fall fashion shows.

HALF-UP HAIR

Where we saw it: Nina Ricci (shown), Miu Miu, Giambattista ValliHow to get it: "It's dream hair—very French, ultrafeminine, and beautiful," said Guido of the voluminous half-up hair at the Nina Ricci show. To create it, he first applied Redken Velvet Gelatine 07 Cushioning Blow-Dry Gel from midshaft to ends, and Redken Aerate 08 Bodifying Cream-Mousse at the crown, before blow-drying the hair with a tiny one-inch round brush. He then formed pin curls and left it all to cool. Once the hair was released, Guido created a center part, lightly teased the hair at the roots, and then pulled back a one-inch section of hair from above both ears and secured it loosely. "These pieces will fall out," he said. "It's very casual."
